Read this excerpt from a blog.
When I eliminated gluten from my diet, my energy level increased. My morning bagel used to make me want a nap around 10:00 a.m., but this week was different. I started each day with an egg, and I was satisfied until lunchtime. A one-egg omelet with peppers and onions was the most flavorful option I tried. I’ll post full menus and pictures tomorrow.
